NASA boss questioned Goddard library review, emails show
Two weeks earlier, a Goddard official learned the GSA needed no manifest for the books NASA was giving up.

Our most lasting houseware purchase was a set of napkin rings for the whole family when the kids were entering grade school. Used them regularly ever since.

Here’s the context: “Saint John Chrysostom, one of the greatest preachers of the early Church, drew a direct line between the liturgical table and the street when he famously wrote: ‘He who said, “This is my body,” is the same One who said, “I was a stranger, and you did not invite me in.”’”

Back when I was a midshipman in NROTC, we’d refer to the guys from Annapolis as going to the “trade school.” Hegseth sure wants to make it one.

AI agents should be taught what every grad student learns before becoming a TA: “I don’t know” is an acceptable response.

New from us: Anthropic just published scenarios for AI’s possible economic impacts, which range from minimal, to explosive GDP growth of 15% by 2030 as knowledge-worker unemployment hits 18%. I sat down with their co-founder Jack Clark to pick his brains on how they’re thinking about all of this.

As someone thinking professionally about how science might work in an oral culture, this passage seemed right: “Writing is a rigorous process to understand your own thoughts and then lay those thoughts out in a way that convinces or inspires or moves other people. But speaking is not that process.”

This church sits in a rather wealthy neighborhood of Chicago, and I’m reminded of John Chrysostom’s words: "If you cannot find Christ in the beggar at the church door, you will not find Him in the chalice."

The calculator analogy does hold up in the sense that few people taught in a calculator environment know how to do complex calculations, e.g. how to take a square root. By analogy, what complex reasoning skills will people taught in an AI environment lose (or never learn)?

Why Don’t Leftie Candidates Do Better Among Working-Class Voters?
It isn’t that non-college voters are more “moderate.” It’s something else entirely, and it will probably take about a decade to fix, if it’s fixable at all.

Sorry, I missed the nice image of the reverse. The ornamented I might be a diagram of the local part of the rete; the triangle is a puzzle. There seem to be some other faint markings.

Steve McCluskey @stevemccluskey.bsky.social · 25/07/2026
Might they be diagrams related to adjacent stars in a constellation or to the structure of the rete? A zoomed out view of the back of the rete marked with their places would help evaluate those ideas.

The author notes that astronomers studying transits of Venus ignored the astronomies native to the places where they observed. She was unaware that Le Gentil, who went to India for the transit, favorably compared the indigenous calculations of a lunar eclipse with contemporary European methods.

Back to the Future of Wayfinding: Pre-modern astro-navigation in the GPS age

New technologies in the 20th century challenged the need for navigators to look to the stars. The rapid development of radio direction-finding, beam and hyperbolic systems, and finally satellite navigation, promised to make old methods redundant. An unfathomable global system of transmitters and receivers would replace skills in taking sightings and computing with brass and paper tools; the signals from atomic clocks would eclipse the long-fixed shapes of the constellations. 
Yet from the beginning this march of new technology was contested. In the first place, while black-box systems promised to make knowledge of location and direction universally accessible, the cost of equipment raised new barriers. As prices plummeted and precision soared, concerns grew that sailors and pilots might lack the understanding necessary to interpret navigational data, leading to increased risk. It has even been suggested that reliance on technology rewires our brains, making us 
stupider.Meanwhile, as ‘traditional’ techniques became outmoded, interest surged in 
reconstructing the seemingly miraculous methods of the past. Respect for the 
astrolabe-toting heroes of the European ‘Age of Exploration’ was complicated by a 
growing pluralistic awareness that their achievements had been preceded by a suite of skills and senses practised in the Pacific. In the Anthropocene, an instinctive feel for one’s environment seems ever more precious when alone atop a vast ocean.Most recently, fears about the vulnerability of GPS systems to jamming or even spoofing have become stronger – and more realistic. Put together, these pressures have caused hydrographic offices and training schools to pull back from abandoning old materials and methods. This paper will survey the arguments of manufacturers and mapmakers, technologists and traditionalists – from the backstaff to the blue dot – to show why, in the age of Google, navigation is so contested.

“The Church has a preferential option for the poor.… It’s a formal doctrinal position,… It means a living wage is not a socialist plot but a human right. Catholic social teaching insists on this point so often and explicitly that you have to work hard to miss it. Vance works hard to miss it.”
